Tunable liquid crystal optical device |
| abstract |
A kind of liquid crystal optical device, it includes the layer structure of the liquid crystal layer with separation, and the layer structure has the alignment surfaces for the pre-tilt angle that contrary sign is limited in liquid crystal material.Four layers of liquid crystal layer can provide the both direction of linear polarization.In the case of lens, the device can be gradient-index lens, and the alignment surfaces have the consistent pre-tilt in space. |
